Ok, to the best of my knowledge:
Is it worth the extra $$$? Only you can answer that. Note that there is a %50 deductible on warranty work. Compare that with $0 deductible for a new car. Also note that the CPO warranty is not an extended service plan.
Cheers and Merry Christmas

You mean $50 deductible right? because it's so pointless to get %50 deductible.
